DEVICE ron SANITARY 'rrr-inmune or MILK.

Y Application Vfried November is, 192s. semaines/19,265.

My invention has reference to an improyement in the art oi sanitary handling of iiood products and more particularly to an im- Jrovement in the sanitary handling oi milk. Milk when lett at a house by a milk dealer, is usually lett outside at an early hour and unprotected and in warm or hot weather, it nay be so left as 'to spoil in a short time.

The object of my invention is to improve a 30 device tor the sanitary handling otl milk whereby, when the bottled milk is'placed in the handling device, the receiver is instantly notiied'that the milk isV delivered, such device being also provided with means for raising the bottled milk to any upper story in which the tenant resides. I

Another object of my invention is to protect the milk containers or bottles, so that animals, suchas cats and dogs,fcannot conl taminate the milk containers or bottles.

A Vinal object oi' my invention is to simplify the construction of such a device for the'sa'nitary handling of milk, whereby the device may be-installed in new or old tenement or apartment houses, at a minimum cost.

My invention consists in the peculiar and novel construction of a device for sanitary handling of milk, said device having details of construction as will be more fully set forth hereinafter and claimed.

Figure 1 is a face View of a portion'o the outer wall of a two storied tenement or apartment house provided with my improved device for sanitary handling of milk and showing the central-portion or" the wall broken away to more clearly show my invention.

holding member 19. A milk bottle compartsanitaryY handling. of milk,"fwhich is also con- 'strncted to handle mail and small packages and 8 a modified lform of thevdevice.

The wall 6 has the usual'mner portion 9 60. formed oflaths and plaster, the outer por- Ytion 10 formed of `boarding and clap-boards separated by vertical studdings 11, 11, `'Lorining an inclosed vertical" space 12,111 the form of a rectangular shaped chute, which in a two storiedt-enement house, extends the height oi the' outer wall and this" space 12,

is utilized tor the reception of my improved device for the sanitary yhandling of milk.

ln carrying rny invention into Vpractice for a two storied two tenement house, "a outer entrance doorway 13 "is cut through the outer portion lO of the wall@ at the lower story and-closedl by a door 14, an inner egress doorway 15 isv cut through'the portion 9 ot the wall't at the upper story or tenement and closed by a ldoor 16 and vertical guide ways 17, 17, are secured centrally to the studdings 11, 11, as shown in Any usual co Lstruction 'S0 of double iire doors 18, 18, are placed in the space 12 on a liiie with the iioor of the upper tenement, as. shown in Figures 2 andV 3. rEhe doors V14 and 16 Yare 'hinged tothe door frames and may be provided with locks, not shown.

Slidably secured to the vertical guide ways 17, 17 is a milk bottle holding inember 19 constructed to form the following vertical sides 20,` 20 terminating in upper 90 ends 21, 21, and lower ends 22, 22, shaped to open the iire doors 13, 13, on the upward and downward Vn'ioveinentso't the milk bottle ment 23 open front and back and havingA on its `bottom spring milk bottle holding clips 24, 24, an upper mail-box 25 closet by an outer hinged door 2G and an inner hinged door 27 and a lower compartment 2S open 'front and back for small mail packages. This compartment 23 may valso Vbe closed by hinged doors, it desired. Below the milk bottle holding member 19 is a lower horizont-al strut 29 secured at eaclrend tothe studdings 11, 11, andonthis strut 29 is a central electrical contact member f30l and on the Istrut 29 and extendingover and normally out ot Contact with the contact meinber30, is afcurvedspringA 31, having a wire connection 32, as shown in Figure 3.

A ille wire 33 goes fromv ther spring wire connection 32 to a battery 34, a wire 35goes from the battery 34 to an electric bell'36 located in the upper tenementand la wir-e 37 goes .from the bell 36 to the electrical contact member 30.` An upper horizontal lstrut 38, i Vin the upper tenement, is Secured at each,

end tothe studding 11 and a similar strut 39 is Secured to the studding 11 vand a vertical Support 40 is secured in place, as shown in Figure 3. Grooved pulleys 41, 42, 43 and 44 are secured to the studding and upper strut.

AA rope 45 secured at its lower end to the yce milk bottle holding member 19, goes upwards overthe pulleys 41 and 42 and to a counter balance weight 46.y An operating rope 47 secnredat its lower end to the milk bottle holding -in-ei'nber 19, goes upward over the pulleys 43 and 44 and then downwards to areel 48 rotatably'V supported in bearings on a studding 11 and support 40. A hand crank 49 is rotatably supported in bearings on a studding 11 and the support 4() and this handicrank 49 is operatively connected to a pinion 50, meshing with a gear 51 fixed to the reel 48. A hand pawl`52 is pivotly secured to the support 46 in aposition to engage with the gear 51. A doorway 53 closed fby a door 54, is formed in the inner portion 9 of the wall 6 for access to the hand crank 49. i

i lVlien in' use the operation is as follows. lVlien a milk dealer delivers the milk, he opens the lower outer door V14 and places the full bottles of milk in the milk bottle compartment23 of the milk bottle holding member 19. milk causes lthe milk bottle holding member to sink downwards against thetension of the curved spring 31 and depressingV the spring 31 causes it to contactwitli'the electrical contact member 30, thereby through the wires'33, battery 34, wire35, electric 19, through the doorway7 15, by opening the door 16. Empty milk bottles are now placed in the milkbottle holding member 19` and the above operations reversed. rIhe milkman removes the empty milk bottles from the milk bottle holding member 19 which has now reached the lower or street posie tion, as shown in Figure 3, which shows the spring 31 out of electrical contact with the electrical contact member 30, the empty milk bottles having insuficient weight to rIhe weight 'of the full bottles of tenant, thus eliminating, as heretofore, the

necessity of the' upper tenanty from going down lto the first or streetfioor to receive milk, mail or small packages.

I do not con'ine myselfI to the exact construction shown, as thesame may be modified within the scope ofthe appendedclaims.

Having thus described my invention I claim as new z 1. In a device of the kind described, in combination with. the outer wall of a house having a vertical chute connecting the lower story with an upper story, said chute haviiigfa lower outside entrance oijiening andan upper inside egress opening, milk bottle rece: Ying receptacle havingrw an entrance opening kand an egress opening, spring'clips for detacliably Vsecuring vthe milk bottlesvin place, means .forr raising the milk bottle re- `celvingreceptacle to an upper story and antoii'iatic means for signallingfthe upper story that the milk has been placed in the milk bottle receiving receptacle.

2, In a device of the kind described, the combination with a vertical movable device 7 inthe form of a box'having a shelf for holding a milk bottle, of an automatic electric signaling device comprising a iizredelec-v tric contact member 30, a curved spring 3l V`over the contact member 30k and havingV an electric wire connection32, a wire 33 Aconnecting the connection32 with a battery 34,..

whereby the weight ,of full bottles of milk in the device 7 will cause the spring 31 to contact with the contact member 30 and ring the bell.

3. In a device of the kind described, the combination of the following instrumentalities, a milk handling device T slidably secured inr ar vertical space in the wall of a house, said device having a milk bottle holding compartment 23, anr upper mail box 25, a lowerparcel compartment an elevating device comprising a reel 48 rotatably supporte ed in bearings, pulleys 43 and 44 rotatably supported on bearings, a rope 47 secured at its lower end to the milk handling device `7, saidrope going over the pulleys 4 3 and and wound on the reel 48, a 51 fixed to the reel 48, a pawl 52 engaging the ygear 51 and a hand crank 49 rotatably supported in vbearings and hav-ing a pinion 50 meshing WILLIAM LAVA'LLEE.
